(EN) EMULATING PARAMETERS OF A FLUID EJECTION DIE
(FR) PARAMÈTRE D'ÉMULATION D'UNE FILIÈRE D'ÉJECTION DE FLUIDE
Abrégé
(EN)
An integrated circuit includes thermal tracking logic, control logic, and an output interface. The thermal tracking logic determines a temperature of a fluid ejection die. The control logic defines an emulated parameter of the fluid ejection die as a function of the temperature of the fluid ejection die. The output interface outputs the emulated parameter to a printer system based on the function and the temperature of the fluid ejection die.

Circuit intégré comprenant une logique de suivi thermique, une logique de commande et une interface de sortie. La logique de suivi thermique détermine une température d'une filière d'éjection de fluide. La logique de commande définit un paramètre émulé de la filière d'éjection de fluide en fonction de la température de la filière d'éjection de fluide. L'interface de sortie délivre en sortie le paramètre émulé sur un système d'imprimante sur la base de la fonction et de la température de la filière d'éjection de fluide.
